Is indentation required in java?
Indentation. The compiler cares nothing about indentation, but if you indent well, you make your code so much easier to read, which means you’ll make it easier to debug. Indentation allows the physical layout (how the code appears on the screen) to match the logical layout (what the code means).

What are clean code principles?
Clean Code Principles. A design principle originating from the U.S. Navy that goes back to 1960 already. It states that most systems should be kept as simple as possible (but not simpler, as Einstein would have said). Unnecessary complexity should be avoided.
Why are coding standards important in Java Development?
Why Coding Standards are Important? Coding Standards lead to greater consistency within your code and the code of your teammates. Easier to understand Easier to develop Easier to maintain Reduces overall cost of application 3.
